The pressure testing of the pipelines associated with the fluidized bed unit in the Fuhai Innovation Pipeline Tunnel project was completed successfully

Thread Content

On December 7, the Fuhai Innovation Pipeline Project, constructed by the Fujian branch of China National Chemical Engineering Corporation’s 13th Construction Company, successfully completed the pressure testing of the pipelines required for the trial operation of the fluidized bed residue hydrogenation unit. This achievement laid a solid foundation for carrying out subsequent tasks such as pipeline purging and anti-corrosion/insulation work. This pressure testing covers three areas: new pipe galleries, the renovation of existing pipe galleries, and the renovation of old tank farms. It involves 205 pipelines, made of materials such as 20# series steel pipes, 20G pipes, and stainless steel pipes. The pipe diameters range from DN50 to DN1500, with a design pressure of 1.0~10.44 MPa; these pipelines include those for auxiliary services, as well as those used for transporting critical materials such as hydrogen and flare gas. To ensure the efficient progress of the pressure testing work, the project team carefully planned and organized the process, optimized the testing plan, and assigned experienced technicians to monitor the data throughout the process and ensure quality control ； All participating units provided full cooperation, responding to inspection requirements around the clock, and accompanied the pressure testing of high-pressure pipelines with large diameters throughout the night to ensure that all aspects complied with relevant standards, thus successfully completing the pressure testing tasks. Next, the project team will maintain a high level of enthusiasm, strictly adhere to the standards of quality and safety, and make steady progress in the project’s completion, thereby helping to ensure its early operation and effectiveness.
